Toa'tt whom/Fit may concern: I

Be it known that 1,:Ronn1rr N. WEST, a

citizen of the United States residing at Brooklyn, in the county of and State of New York, have invented new and useful Improvements in ashing-Machine Cylinders, of t which the following i is a specification. a I i t a Reference be had to the accompany- 0, ing drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer a to similar parts intheseveral figures therein.

This invention relates more particularly to washing machine cylinders of the type soiled articles of clothing,

Such cylinders :are rotatively operated commonly used in laundries fol washing,

firstin one direction and then in the op- ,posite direction means :of suitable meche anism as is Well understood in the art. V

For this purpose the cylinder lspirovlded with a shaft projecting from oneof itsends to whichishalft thedriving poweris applied by suitable mechanism.

This driving shaftis mounted upon. the end or headof the cylinder by means of a supporting-plate which is bolted to the head of the cylinder. 1 y

The continued reversing movements ofthe cylinder soon causes these bolts to circularly elongate the holes in the head through which the bolts pass so that after a greater or less period of use the shaft-supporting plate ceases to be properly secured upon the head.

The principal object of the present invention is to relieve from, this excessive strain the bolts whereby the sh aft-supp0rtingplate is secured to the head of the cylinder.

Fig. 1 of the drawings 1s an end vlew of a washing machme-cyl1nder made in accordance with my invention.

tlti

1' ribs, 1, two heads, 2, only one of which is Fig. 2 is a vertical section taken on the broken line 2-8 in Fig. 1.

Fig. 3 is a longitudinal section taken on the broken line 33 in Fig. 1.

Fig.4 is a view in perspective of one of the clamp-plates detached.

Referring to the drawings wherein, the invention is shown in preferred form, the cylinder 18 made up of four longitudinal shown, andvstaves, 3, interposed between neighboring ribs, 1.. a

These parts-are usually made of wood, and the cylinder thus ii ormed. is rotatively mounted within a casing, fl,

ln carrying out my invention, I extend the ribs, 1, beyond the head, 2, as shown Upon the head, 2, I mount a shalt-supporting plate, 5, which ispreferably secured to thehead by bolts, .6, in the usual manner.

From the plate a shaftn'i', projects out through the neighboring end of the casing, 1-, to receive the driving mechanism comprising in part a pinion, 8, fixed on said shaft whereby rotative movements in opposite directions can be imparted to the shaft. t

The shaft-supporting plate, 5, is formed with abutments, 9, on opposite sides of, and spaced away from the projecting ends, 1 of the respective ribs, 1. v v v In the spaces thus providedbetween the abutments, 9., and the ends,,;-1 ,ofthe ribs, I apply toopposite sides of the respective rib-ends, 1, clamp-plates, 10, engaged by suitable screwemechanism interposed between the clainp-plates and abutments 9.

The clamp-plates, 10, are made of metal and are preferably formed with spurs, 11, on their inner sides, which spurs are adapted to penetrate the ends of the wooden ribs.

Each clamp-plate is also preferably provided with a central aperture, 12, adapted to freely receive a screw-bolt.

As a preferred form of screw-mechanism for clamping the clamp-plates, 10, firmly upon opposite sides of the respective ribends, 1 l have shown a screw-bolt, 13, having an angular head, 14, seated in an angular recess, 15, formed in the neighboring: side of the abutment, 9, the screw-end of the bolt being adapted to play freely in the aperture, 12, in the neighboringclampplate, 10, said screw-bolt having thereon a side of end of the bolt a sufiicient distance to permit the bolt and the neighboring clamp-plate to be interposed between the abutment, 9, and the neighboring rib-end, 1, after which the nut, 16, is set up so as to drive and clamp said clamp-plate against the neighboring side of the rib-end, 1, thereby seating the spurs, 11, in the rib-end.

- By means of my invention the thrust of the shaft-supporting plate, 5, is transmitted directly to the ribs, 1, instead of directly to the head of the cylinder as heretofore.

The bolts, 6, are thus relieved otall or practically all of this thrust, and are re lieved from the tendency to elongate the holes through Which they pass.

Lost-1notion can at any time be readily taken up by means of the nuts,'16, so that there is no tendency for the parts to be come worn by a relative movement between the shaft-supportingplate, 5, and the cyl inder as was the case where the thrust of the shaft-supporting plate, 5, was transmitted to the head of th'ecylinder by the bolts.

While I have shown'and described the invention in its application to a washingmachine-cylinder, it is also applicable to any cylinder operated under similar conditions.

What I claim as new and desire to secure by Letters Patent is 1. In a device of the class described and in coinbinatioma cylinder having a head, and a'rib projecting beyond the head; a shaftsupport secured to the head and formed with abutments on opposite sides of and spaced from the projecting end of said rib; clampplates on opposite sides of the projecting end of said rib; and screw-mechanism between the respective abutments and clamp plates.

2. In a device of the class described and in combination, a cylinder having a head, and a rib projecting beyond the head; a shaftsupport secured to the head. and formed with abutments on opposite sides of and spaced from the projecting end 01'' the rib; apertured clamp-plates engagcable with the opposite sides oi" the projecting end of the rib; screw-bolts having heads in non-rotative engagem'ent with the respective abutments, the

screw-bolts having heads in non-rotativc cngageinent with the respective abutments, the inner ends 01" the bolts being ireely movable within the respective apertures in the clampplates; and nuts fitting the respective bolts and engageable with the respective clampplates.

Intestimony whereof, I have hereunto set my hand this 21st day of October, 1921.
